[QUOTE="FindSumStuff, post: 653601, member: 17983"] The soft iron bar put across the magnet to short the magnetic field is called a keeper. It helps preserve the field strength of older style alnico magnets. Super magnets tend to permanently loose field strength when getting too hot say more than about 80 deg C. Especially a pain in stepper motors. [/QUOTE]
